Abstract

PROBLEM TO BE SOLVED: To provide an opening and closing member control device for performing the opening and closing control of an opening and closing member on the basis of the detection of its opening and closing position, which can surely perform the origin position set of the opening and closing position. SOLUTION: When a normally closed switch SW3 is subjected to a prescribed operation (operated for a prescribed time or more) to operate a roof glass to a full close side in the state where the glass is arranged in a mechanical critical position on the full close side, a control part 13 sets the opening and closing position of the roof glass arranged in this position as a temporary origin position. When the roof glass is then operated from the temporary origin position to a mechanical limit position on the full open side, the control part 13 compares the operation quantity during it (operation count number) with a preset regulated quantity (regulated count number), and sets the temporary origin point as origin point when the operation quantity (operation count number) is the regulated quantity (regulated count number) or more.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing member control device for controlling the opening / closing operation of an opening / closing member such as a roof glass, a window glass, and a sliding door of an automobile, and a method of setting the origin position of the opening / closing member in the opening / closing member control device. Things.

[0002]

2. Description of the Related Art Conventionally, some sunroof devices mounted on an automobile are provided with an automatic opening / closing switch in addition to a normal opening / closing switch in which a roof glass slides and opens only during operation. Once the auto-open switch is operated, the roof glass slides open from the fully-closed position to the fully-opened position at once without the need for subsequent operations. Similarly, an automatic slide closing operation is performed in which the roof glass slides from the fully open position to the fully closed position at a stretch. A sunroof device that performs such an automatic opening / closing operation generally has a function of detecting the entrapment and reversing the roof glass in a fully open direction when a foreign object is entrapped during the automatic slide closing operation of the roof glass. .

[0003] A sunroof device having such a function is usually provided with a rotation detecting device for detecting the rotation direction and rotation period of a drive motor. The device has a pair of rotation sensors arranged to output output signals (pulse signals) having different phases from each other based on the rotation of a drive motor. The device detects a rotation cycle of a drive motor based on an output signal (pulse signal) output from a rotation sensor and utilizes a phase difference between output signals (pulse signals) output from the respective rotation sensors. Detects the rotation direction of the drive motor. The sunroof device counts the rotation cycle of the drive motor, and detects the open / close position of the roof glass by adding the count in, for example, the opening direction and subtracting the count in the closing direction, and detects the rotation direction of the drive motor. The opening / closing direction of the roof glass is detected, and the opening / closing control of the roof glass is performed based on the detection. Therefore, such a sunroof device is
Conventionally, the count number for recognizing the open / close position of the roof glass is set to “0” when the origin position of the open / close position of the roof glass is set, for example, when the roof glass is arranged at the mechanical limit position on the fully closed side. Is set as follows.

[0004]

In setting such an origin position, the roof glass may sandwich foreign matter such as dust. In this case, the sunroof device is set as the origin position (the count number “0”) even though the actual roof glass is shifted from the origin position in the opening direction. Therefore, a difference occurs between the open / close position of the roof glass based on the count number and the actual open / close position of the roof glass, which causes a malfunction. Therefore, in the sunroof device having the above-described configuration, it is required that the origin position of the open / close position of the roof glass be reliably set.

Incidentally, the roof glass 4 of the present embodiment is shown in FIG.
As shown in (1), there are mainly a fully closed position (origin position), a fully tilted position, a pseudo fully closed position, a flap down position, and a fully open position. The roof glass 4 disposed at the fully closed position first performs the tilt opening operation from the position, and temporarily stops at the tilt fully opened position. Next, when the roof glass 4 is opened again, the roof glass 4 is tilt-closed from its fully opened position to reach the pseudo fully closed position, from which flap down operation (further downward movement toward the indoor side) is performed, and the slide is fully opened. Open the slide to the position. That is, in this opening operation, the roof glass 4 can be opened by a single opening operation from the fully closed position to the fully tilted position, and can be opened by one opening operation from the fully opened position to the fully sliding position. Has become. On the other hand, the roof glass 4 arranged at the slide fully open position

That is, in this closing operation, the roof glass 4 can be closed from the fully open position to the fully closed position via the pseudo fully closed position by one closing operation.

The drive motor 5 includes a drive unit 1 together with a drive control circuit 11 described below for controlling the drive of the motor 5.
0. The drive unit 10 is disposed between the roof panel 2 in front of the skylight 3 and a molded ceiling panel (not shown) on the indoor side.

FIG. 1 is an electric block diagram for explaining an electric configuration of a sunroof device for controlling the driving of the driving motor 5. As shown in FIG. Drive control circuit 1 for controlling drive of drive motor 5
1 is connected to a battery (not shown), and a driving power supply + B is supplied to the circuit 11 from the battery. Drive power supply + B
Is controlled to a predetermined power supply voltage by the power supply circuit 12 in the drive control circuit 11 and controlled as detection means, open / close control means, provisional origin position setting means, comparison means, origin position setting means, control means and notification means. It is supplied to the unit 13.

The drive control circuit 11 is connected to an ignition switch SW1. Ignition switch SW
1 is connected to the control unit 13 via the input circuit 14 in the drive control circuit 11. Ignition switch S
When W1 is operated, W1 outputs an operation signal (ON signal) to the control unit 13 via the input circuit 14. The control unit 13 operates based on the drive power supplied from the power supply circuit 12 based on the ON signal of the ignition switch SW1.

The drive control circuit 11 includes various switches SW2 to SW for opening and closing the roof glass 4.
5, ie normally open switch SW2, normally closed switch SW
3. Auto open switch SW4 and auto close switch S
W5 are respectively connected. Various switches SW2 to SW
5 is connected to the control unit 13 via the input circuit 14 in the drive control circuit 11. Various switches SW2 to SW
5 are each operated to output a command signal (ON signal) to the control unit 13 via the input circuit 14.

A reference clock signal necessary for the operation of the control unit 13 is input to the control unit 13 from a clock transmission circuit 15. The control unit 13 monitors the drive power supplied from the power supply circuit 12 by the voltage monitor circuit 16.

The control section 13 supplies drive power to the drive motor 5 via a drive circuit 17 to
Control. Specifically, the control unit 13 performs the normal opening operation (manual opening operation) of the roof glass 4 while the normal opening switch SW2 is being operated, that is, while the ON signal is being input from the switch SW2. A drive power is supplied to the drive motor 5 to drive the motor 5. Stop the operation of the normally open switch SW2, that is, the switch SW2
When the off signal is input from the control unit 13, the control unit 13 stops supplying the drive power to the drive motor 5 so as to stop the operation of the roof glass 4. In this case, the detection of the open / close position of the roof glass 4 described later
Is disposed at the tilt fully open position (see FIG. 2), the control unit 13 stops supplying the drive power to the drive motor 5 even if the normally open switch SW2 is operated, and stops the drive of the motor 5. Pause. Then, the normally open switch S again
When W2 is operated, the control unit 13 supplies power to the drive motor 5 to cause the roof glass 4 to perform the tilt closing operation and the sliding opening operation.

On the other hand, the control unit 13 has a normally closed switch SW.
While the switch 3 is being operated, that is, while the ON signal is being input from the switch SW3, drive power is supplied to the drive motor 5 in order to normally close the roof glass 4 (manual close operation). Drive. When the operation of the normally closed switch SW3 is stopped, that is, when the off signal is input from the switch SW3, the control unit 13 stops supplying the driving power to the driving motor 5 so as to stop the operation of the roof glass 4.

The control unit 13 has an automatic opening switch SW.
4 is operated once, that is, once the ON signal is input from the switch SW4, the roof glass 4 is moved from the fully closed position to the fully open tilt position or to the fully open tilt position even if an OFF signal is subsequently input from the switch SW4. The drive power is supplied to the drive motor 5 so as to perform an automatic opening operation in which the slide is fully opened from the position to the slide fully open position, and the motor 5 is driven. When the control unit 13 detects that the roof glass 4 is located at the tilt fully open position or the slide fully open position by detecting the open / close position of the roof glass 4 described later, the control unit 13 switches the drive power to the drive motor 5. Then, the operation of the roof glass 4 is stopped. That is, also in this case, when the control unit 13 is disposed at the tilt fully open position, the control unit 13 stops supplying the driving power to the driving motor 5 and temporarily stops the driving of the motor 5.

On the other hand, the control unit 13 has an automatic closing switch S
Once the W5 is operated, that is, once the ON signal is input from the switch SW5, even if the OFF signal is subsequently input from the switch SW5, the automatic operation of closing the roof glass 4 from the fully open position to the fully closed position at once is performed. A drive power is supplied to the drive motor 5 to perform the closing operation, and the motor 5 is driven. The control unit 13 controls a roof glass 4 described later.
When the open / close position is detected to detect that the roof glass 4 is located at the fully closed position, the drive power supply to the drive motor 5 is stopped, and the operation of the roof glass 4 is stopped.

The drive control circuit 11 includes a drive motor 5
Hall element magnetic sensors 18a, 18 as a pair of rotation sensors for detecting the rotation cycle (rotation speed) and rotation direction of the
b is provided on a substrate constituting the circuit 11. More specifically, a multi-pole magnetized sensor magnet is provided on a rotation shaft (not shown) of the drive motor 5 so as to rotate integrally therewith. A Hall element magnetic sensor 18a, 18b are arranged at a predetermined interval from each other in the rotational direction. That is, a non-contact type rotation sensor using magnetism is used as the rotation sensor of the present embodiment. Each Hall element magnetic sensor 18a, 18b
When the drive motor 5 rotates, it outputs a pulse-like output signal corresponding to the rotation of the motor 5 to the detection circuit 19. The output signals (pulse signals) output from the Hall element magnetic sensors 18a and 18b have a phase difference (for example, 1/2 cycle) from each other. Detection circuit 19
Output to the control unit 13 by shaping the waveform of each output signal (pulse signal).

The control unit 13 controls the drive motor 5 based on the cycle of an output signal (pulse signal) input from each of the Hall element magnetic sensors 18a and 18b via the detection circuit 19.
The rotation cycle (rotation speed) of is detected.

That is, when the normal open switch SW2 and the automatic open switch SW4 are operated and an ON signal is input, the control unit 13 controls the output signal (pulse signal) every cycle (for example, based on the rising edge). T) Add "1" to the count number (see FIG. 2). On the other hand, the control unit 13
When the normal close switch SW3 and the automatic close switch SW5 are operated and an ON signal is input, "1" is subtracted from the count added when the output signal (pulse signal) is opened at each cycle. . And the control unit 13
Detects the open / close position of the roof glass 4 according to the count number.

As shown in FIG. 2, in this embodiment,
When the count number becomes “10” or less, it is considered that the roof glass 4 is arranged at the fully closed position. Further, when the roof glass 4 is arranged at the tilt fully open position, the count number becomes “110”, and when the roof glass 4 is arranged at the pseudo fully closed position, the count number becomes “187”. When the roof glass 4 is arranged at the flap down position, the count number becomes “230”, and when the roof glass 4 is arranged at the slide fully open position, the count number becomes “916”. The count number between "230" and "236" (slide A area in FIG. 2) is a load reversal mask area in which the entrapment determination described below is not performed. That is, the pinch determination is performed when the count number is between “236” and “916” (slide B area in FIG. 2). When the roof glass 4 is disposed at the mechanical limit position on the fully open side, the count number becomes “1000”. The relative relationship between the roof glass 4 and the count number is determined by setting the origin position of the roof glass 4 described later (in the present embodiment, the roof glass 4
Is set at the mechanical limit position on the fully closed side, and the count number is set to “0”).

The control unit 13 detects the rotation direction of the drive motor 5 according to the phase difference between the output signals (pulse signals), and opens and closes the roof glass 4 based on the detection of the rotation direction of the drive motor 5. The direction has been detected.

While the roof glass 4 is performing the automatic closing operation in the slide B area shown in FIG. 2, the control unit 13 determines that the rotation cycle (rotation speed) of the drive motor 5 is greater than a predetermined pinch determination value. If the length is longer (slower), it is determined that the foreign object is sandwiched between the roof glass 4 and the roof panel 2 and the rotation cycle is longer (the rotation speed is lower). Then, the control unit 13 rotates the drive motor 5 in a reverse direction to release the foreign matter caught by the roof glass 4 during the closing operation, and opens the roof glass 4 by a predetermined count (load reversal operation). At this time, the control unit 13 switches the count number from the subtraction to the addition based on the reverse rotation of the drive motor 5.

Next, the procedure for setting the origin position of the roof glass 4 will be described with reference to the flowchart shown in FIG.
Before setting the origin position of the roof glass 4, the automatic opening and closing operation of the roof glass 4 is prohibited.

In step S1, the controller 13 determines whether the setting of the origin position of the roof glass 4 has been completed. If the origin position has been set, the control unit 1
Step 3 ends the origin position setting process. On the other hand, if the setting of the origin position is not completed, the control unit 13 proceeds to step S2.

In step S2, an operator (setter)
Operates the normally closed switch SW3, and when an ON signal is input from the switch SW3 to the control unit 13, the control unit 13
Proceeds to step S3.

In step S3, the control unit 13 determines whether or not the roof glass 4 is located at the mechanical limit position (mechanical lock position) on the fully closed side by operating the normal close switch SW3. That is, when the rotation speed of the drive motor 5 becomes “0”, the control unit 13 determines that the roof glass 4 is located at the fully closed mechanical lock position. Roof glass 4
If is not located at the fully closed mechanical lock position, the control unit 13 returns to step S2 and repeats the above processing. Then, when the roof glass 4 is disposed at the fully closed mechanical lock position, that is, when the rotation speed of the drive motor 5 is detected to be “0”, the control unit 13 starts time counting by a timer 13a provided therein, Proceed to step S4.

In step S4, the control unit 13 determines whether a predetermined time has been measured by the timer 13a. If the predetermined time is not measured by the timer 13a, the control unit 13 returns to step S2. That is, the control unit 1
3 is a roof glass 4 when the normally closed switch SW3 is operated.
Steps S2 to S4 are repeated until a predetermined time elapses in a state where is disposed at the fully closed mechanical lock position. Note that, during this predetermined time, in order to set the origin position of the roof glass 4, even though the glass 4 is in the fully closed mechanical lock position, the operator is required to set the normal closing switch S
The control unit 13 determines that W3 has been operated for a predetermined time or more.
Is set to the length to be recognized. Then, when the predetermined time is measured, the control unit 13 proceeds to step S5.

In step S5, the control unit 13 stops the power supply to the drive motor 5, and
The normal closing operation (manual closing operation) based on the operation of W3 is stopped, the position of the roof glass 4 arranged at the fully closed mechanical lock position is set as the temporary origin position, and the count number is set to “0”. Then, the control unit 13 performs step S
Proceed to 6. At this time, the control unit 13 permits the automatic opening and closing operation of the roof glass 4.

In step S6, when the operator operates the automatic opening switch SW4 and the roof glass 4 automatically operates in the fully opening direction from the temporary origin position, the control unit 13 proceeds to step S7.

In step S7, the control unit 13 determines whether the roof glass 4 is located at the mechanical lock position at the mechanical limit position (mechanical lock position) on the fully opened side, that is, whether the rotation speed of the drive motor 5 has become "0". judge. Roof glass 4
If is not located at the fully open mechanical lock position, the control unit 13 proceeds to step S8, adds the count number, and proceeds to step S6 again. That is, the control unit 13
Increments the count number until the roof glass 4 is located at the fully opened mechanical lock position. When the roof glass 4 reaches the fully opened mechanical lock position, the control unit 13
Proceeds to step S9, stops the supply of drive power to the drive motor 5, and stops the automatic opening operation. Then, the control unit 13 proceeds to step S10.

In step S10, the control unit 13
It is determined whether or not the operation amount (operation count number) of the current automatic opening operation is equal to or greater than a specified amount (specified count number) stored in advance in the storage unit 13b in the control unit 13. If the operation amount is equal to or more than the specified amount, the control unit 13 proceeds to step S11, and sets the temporary origin position determined in step S5 as the origin position,
The relative relationship between the open / close position of the roof glass 4 and the count number is determined. Then, the control unit 13 proceeds to step S12, permits the subsequent automatic operation, and ends the origin position setting flow of the roof glass 4. And the control part 13
The open / close position of the roof glass 4 is detected based on the count number, and various opening / closing operations are controlled according to the detected position.

On the other hand, if the operation amount (operation count number) of the roof glass 4 is smaller than the specified amount (specified count number) in step S10, the control unit 13 proceeds to step S10.
Proceeding to 13, it is determined that the temporary origin position determined in step S5 is erroneously recognized. That is, the control unit 13 erroneously recognizes the position where the roof glass 4 moves in the opening direction due to the roof glass 4 holding the foreign matter when the roof glass 4 is disposed at the fully-closed mechanical lock position as the temporary origin position. It is determined that the operation amount of has decreased. In this case, there is a difference between the open / close position of the roof glass 4 based on the count number and the actual open / close position of the roof glass 4, and therefore, the automatic opening / closing operation that depends only on the detection of the open / close position of the roof glass 4 based on the count number. May cause problems.

Accordingly, the control unit 13 proceeds to step S14, prohibits the subsequent automatic opening / closing operation, and ends the flow of setting the origin position of the roof glass 4. In this case, since the automatic opening / closing operation cannot be performed even though the origin of the roof glass 4 has been set, the operator (setter) can easily recognize that the origin cannot be set normally.

As described above, the sunroof device of the present embodiment has the following features. (1) In the present embodiment, the normal closing switch SW3 is operated (operated for a predetermined time or more) to operate the roof glass 4 in the same direction while the roof glass 4 is disposed at the mechanical limit position on the fully closed side. Then, the open / close position of the roof glass 4 arranged at the position is set to the temporary origin position. Next, when the roof glass 4 is operated from the tentative origin position to the mechanical limit position on the fully open side based on the operation of the automatic open switch SW4, the operation amount (operation count number) during that time and the predetermined amount (operation number) are set. Is counted, and when the operation amount (operation count number) is equal to or more than the specified amount (specified count number), the temporary origin position is set to the origin position. That is, if the operation amount (operation count number) is less than the specified amount (specified count number), when the roof glass 4 is disposed at the mechanical limit position on the fully closed side, the glass 4 squeezes foreign substances, and thus the provisional amount is temporarily reduced. It can be seen that the origin position is set to a position moved toward the opening direction. Therefore, by determining the amount of actuation from the temporary origin position to the fully open direction, the origin position can be reliably set.

(2) In the present embodiment, when the setting of the origin position of the roof glass 4 is normal, the subsequent automatic opening / closing operation is permitted, and when the setting of the origin position is abnormal (incorrect recognition). Then, the notification is made by prohibiting the subsequent automatic opening / closing operation, so that the operator (setter) can easily recognize whether the setting of the origin position of the roof glass 4 is normal or abnormal.

(3) In this embodiment, the drive motor 5
Since the drive control circuit 11 having the Hall element magnetic sensors 18a and 18b and the control unit 13 and the like are integrally formed as the drive unit 10, the assembling work of the sunroof device can be facilitated.

The embodiment of the present invention may be modified as follows. In the above embodiment, the origin position of the roof glass 4 is set on the fully closed side, but may be set on the fully opened side.

In the above embodiment, when the normal closing switch SW3 is operated for a predetermined time while the roof glass 4 is disposed at the fully closed mechanical lock position, the temporary origin position is set. However, the present invention is not limited to this. Instead, for example, the temporary origin position may be set when the switch SW3 is repeatedly operated a predetermined number of times within a predetermined time.

In the above embodiment, when the rotation cycle of the drive motor 5 is longer than a predetermined pinch determination value, it is determined that pinch has occurred due to the roof glass 4, but the pinch determination is not limited to this. Not something.

In the above embodiment, the Hall element magnetic sensors 18a and 18b are used as the rotation sensors, but a magnetoresistive element whose resistance changes with a change in the magnetic field may be used.
Further, for example, an optical rotation sensor other than the non-contact type magnetic sensor may be used. Further, a contact type rotation sensor using a sliding contact may be used.

The circuit configuration of the drive control circuit 11 of the above embodiment is not limited to this, and may be changed as appropriate. For example, the control unit 13 performs the above-described various controls collectively. However, a configuration in which a plurality of control units are provided and shared and controlled, respectively, may be employed.

In the above-described embodiment, the drive motor 5 and the drive control circuit 11 having the Hall element magnetic sensors 18a and 18b, the control unit 13 and the like are integrally formed as the drive unit 10, but the invention is not limited to this. Instead, for example, the drive control circuit 11 may be provided separately.

In the above embodiment, the slide roof operation and the tilt opening / closing operation are both performed on the sunroof apparatus. However, the embodiment may be performed on a sunroof apparatus that performs only the slide opening / closing operation. Further, a series of operations of the roof glass is not limited to this, and may be changed as appropriate.

In the above-described embodiment, the sun roof device has a roof glass as an opening / closing member. However, other devices such as a power window device having a window glass as an opening / closing member, a slide door device having a sliding door as an opening / closing member, etc. May be implemented.
